tools: Add cmake toolchain file for cross compilation on arm64 

We need this to cross-compile sof-logger for arm64.

Steps:
	* download and install cross-compiler
	* (e.g on Ubuntu: sudo apt-get install gcc-aarch64-linux-gnu)
	* mkdir tools/build/
	* cd tools/build/
	* cmake .. -DCMAKE_TOOLCHAIN_FILE=../scripts//cross-arch64.cmake
	* make sof-logger
